Lug,

Without a more in-depth analysis, please consider that the 375 ft/lbs of torque in the C5 may happen in a narrow band of the RPM spectrum. Newer engines are becoming better at delivering a flatter torque curve, which means that their torque is available pretty much off the line. Older engines, or different designs, might only deliver that torque at the end of the RPM spectrum, in which case they might not be as good at the initial acceleration on a 1/4 mile. Since this drag run happens in such a small amount of time, this could incur some of the difference.

Just a possibility.
